The carriage l5 supports aplurality ci -pawls l fi; w ch are piveta y. mnt n sl rm e ment with the record playing position, On'the Fig. 3.

It is important that a single. projection" 26 should engage a singlehump 25 of a spring 23 to insure correct hitching of a single tray Illto the carriage l5. The drum 2'! is actuated into any 1 of its variouspositions by selecting means with which thepresent invention is notconcerned, for

example the selecting means shown in the patent 1 above referred to, andthese positions determine. 1 which record is to be played. Rigid withthe drum 2'! and preferably integral therewith is a star'wheel 39 havinga recess corresponding to each'selecting position of the drum 21. Astrong oblique spring 3| carried by the carriage I6 is arranged toengage a roller 32 as the carriage l5 moves to its extreme right-handposition,

forcing this roller into thecorresponding recess of I the star wheel30.. Theroller 32 is carried on a pivoted arm 33 and the arrangement issuch that when the roller32 is nested in one of the recesses 0f the starwheel 30, the corresponding projection is in proper engagement with thehump of the corresponding spring 23 so that the corresponding pawl I8 isfree to move into register with the V-shaped recess of the correspondingrecord tray.

The phonograph is arranged to stop with the record tray of the lastplayed record in its ex-' treme left-hand position and the carriage I5is also in its extreme left-hand p-ositiong 'Consequently when themachine is out of operation, when a record is being played or when thecarriage I5 is in position except at the approaching of its extremeright-hand position the drum 21 may be actuated into'a new selectingposition.

It will thus be seen'that I have provided an of pawls each individual toan individual record,

spring 2 3' from its'normal position. This new 4 ual to each member andnormally effective in said one position of the carriage to displace thecorre-' sponding member out of carrier engaging position, and a selectormeans arranged to displace any single one of said stationary means torender -it inefiective whereby only the correspondingv record is carriedout for reproduction.

2. In an automatic phonograph comprising a plurality of individualmovable. record carriers and a displac'eable'carriage arranged to moveany individual carrier out towards playing'position and back to normalposition, in combination, a series of pawls on said carriage, each in,

dividual to and arranged to engage a corresponding carrier, means onsaid carrier biassing said pawls into carrier engaging position,individual springscorresponding to said carriers and normally engagingthe corresponding pawl in one position of the carriage to move itagainst its biassing means out of carrier engaging position, andselector means arranged to move a single one of said springs out ofengagement with its corresponding pawl whereby said corresponding pawlengages the corresponding carrier.

3. In an automatic phonograph comprising'a plurality of individualmovable record carriers and a displaceable carriage arranged to move anyindividual carrier out towards playing position 7 and back to normalposition,,in combination, a

improved connecting means in which the re-f ciprocating carriage isprovided with a plurality series of pawls on said carriageyeachindividual toand arranged to engage a corresponding carrier, a set ofindividual springs on the carriage biassing said pawls into recordengaging position, a second set of individual springs arranged to engagesaid pawls in one position of the carriage, the springs of the secondset being sufiiciently strong to displace the pawls out of carrierengaging position. against the action of the springs of the first set,and selector means arranged to V engage a single one of the springs ofthe second set displacing it out of engagement with a correspondingsingle pawl, whereby said single pawl engages the corresponding recordcarrier and the corresponding carrier'is moved out by the carriagetowards record playing position.

4. In an automatic phonograph comprising a plurality of individualmovable record carriers and adisplac'eable carriage arranged to move anyindividual carrier out'towards playing position and back tonormalposition, in combination, a

series of pawls on said carriage, each individual toand arranged toengage a corresponding car rier, a'set of individual springs on thecarriage structure obviates any necessity for critical ad-" justment ofthese springs. The only essential is come the natural bias of the spring22.

that the spring 23 be strong enough to over-i Having thus described myinvention, I declare that what I claim is:
